You guys are getting hung up on the wrong thing.  Before talking ports
(which is a non-issue), realize that tordns cannot do an MX lookup.
This remains the biggest hurdle to sending mail.

Postfix must run with a transparent proxy (no SOCKS proxy capability),
so it relies wholly on tordns for MX lookups.  

Torsocks has a (now broken) feature to disable TorDNS.  If tordns
could be disabled, then postfix could do an MX lookup.  It would be a
leak, but at least it would work.  At the moment, the tordns disabler
has been removed, so there is no hope of running a mail
server... Unless someone comes up with a SOCKS-capable mail server.
